Question 1: Describe the three main views used in orthographic projection and explain their purpose.

Answer: The three main views are the front view, top view, and side view. They are used to represent all dimensions and features of an object from different angles, providing a complete understanding of its shape.

Question 2: Identify which view (front, top, or side) would best show the width and height of a box-shaped object.

Answer: The front view shows the height and width of the object.

Question 3: Describe a scenario where orthographic drawings are essential in manufacturing.

Answer: Orthographic drawings are essential in manufacturing to communicate precise dimensions and details of a part to ensure accurate fabrication and assembly.

Question 4: Draw a simple rectangular box and label its front, top, and side views in the space provided.

Answer: A correct sketch would show a rectangular box, with the front view illustrating the height and width, the top view showing the length and width, and the side view displaying the height and depth. Each view should be aligned correctly to represent the object accurately.

Question 5: Sketch an object that is a cube with a small cylindrical hole through its center. Show the front and top views.

Answer: A correct sketch would depict a cube with a circular hole visible in both the top and front views. The hole should be centered and run through the entire object, with the views aligned properly.

Question 6: Explain why orthographic drawings do not include perspective or shading.

Answer: Orthographic drawings do not include perspective or shading because they are meant to show accurate, scaled, and true representations of an object from different views without distortion, focusing on dimensions and shape.

Question 7: Identify the missing view in a typical orthographic projection where only the front and side views are provided, but the top view is absent. Describe what features would be visible in the top view.

Answer: The missing top view would show the length and width of the object, including any features such as holes, notches, or protrusions that are visible from above.

Question 8: Draw a side view of a rectangular prism that has a circular cut-out on one side. Indicate the position of the cut-out in your sketch.

Answer: A correct sketch would show a rectangular prism with a circle on the side face indicating the cut-out, aligned correctly with the other views. The cut-out should be centered or positioned as specified.

Question 9: Describe how you would convert a 3D object into orthographic views. What steps would you follow?

Answer: First, identify the main features of the object. Then, draw the front view, ensuring it shows the height and width. Next, draw the top view showing length and width, and finally, the side view showing height and depth. Ensure all views are aligned properly and scaled equally.

Question 10: Sketch a simple T-shaped object in orthographic projection, including front, top, and side views in the space provided.

Answer: A correct sketch would show the T-shape in all three views, with the front view displaying the T profile, the top view showing the crossbar of the T, and the side view illustrating the depth of the vertical stem and horizontal top.

Question 11: Explain the importance of consistent scale and alignment when constructing orthographic views.

Answer: Consistent scale and alignment ensure that all views accurately represent the same object, making it easier to understand its true shape and size, and preventing errors during manufacturing or assembly.
